This will never work unless you sort the input so that each job comes after all of its predecessors. The data pairs you have represent a directed graph. Provided that that the directed graph is acyclic, such a sort should be possible and this is called a topological sort. Lucky for you, Unix has a program called tsort to do this. Try:
But bear in mind that with a complex directed graph there will probably be several different ways to assign your level numbers. This will find one of them.

I have a requirement to generate positive random 16 and 13 digit numbers.
Here is the script I have so far.....

tsort
tsort(1) General Commands Manual tsort(1)NAME
tsort - topological sort
SYNOPSIS
[file]
DESCRIPTION
produces on the standard output a totally ordered list of items consistent with a partial ordering of items mentioned in the input text
file. If no file is specified, the standard input is understood. is generally used in conjunction with the command to sort the objects to
be installed in a library by (see lorder(1) and ar(1)).
The input consists of pairs of text items (nonempty strings) separated by blanks. Pairs of different items indicate ordering. Pairs of
identical items indicate presence, but not ordering.
EXTERNAL INFLUENCES
Environment Variables
determines the locale for the interpretation of text as single- and/or multi-byte characters.
determines the language in which messages are displayed.
If or is not specified in the environment or is set to the empty string, the value of is used as a default for each unspecified or empty
variable. If is not specified or is set to the empty string, a default of "C" (see lang(5)) is used instead of
If any internationalization variable contains an invalid setting, behaves as if all internationalization variables are set to "C". See
environ(5).
International Code Set Support
Single- and multi-byte character code sets are supported.
DIAGNOSTICS
There is an odd number of fields in the input file.
WARNINGS
Libraries and object files cannot be directly.
uses a quadratic algorithm that is not considered worth fixing given its typical use of ordering a library archive file.
